About me

Since 2021 I build software and run infrastructure in agile teams. I solve complex problems with analytical thinking and rely on pair programming, TDD, and clean code — even in fast-moving environments. As a DevOps engineer I build reproducible, stable systems. As a facilitator I guide decision-making in self-organized teams.
